| 摘要 |
<p>The present invention relates to a recording and reproducing device including a DVD unit, an HDD unit and a VCR unit and an MPEG board which processes both video/audio signals of the DVD unit and the HDD unit and provides a recording and reproducing device capable of efficiently radiating heat of an MPEG IC mounted on the MPEG board. A plane 20a of an MPEG IC 20 mounted on an MPEG board 12 is contacted with a contacting surface 4b of a bottom face 4a of a chassis 4 and heat generated in the MPEG IC 20 is directly radiated over the bottom face 4a of the chassis 4. Furthermore, a cooling fan 7 is placed at the back of a recording and reproducing device 1 and heat radiated over the bottom face 4a of the chassis 4 is cooled with a cooling wind.
